Soluble cell adhesion molecules in patients with acute coronary syndrome.
To observe the changes in serum soluble intercellular adhesion molecule type-1 (ICAM-1), vascular cell adhesion molecule type-1 (VCAM-1), E-selectin and von Willebrand factor (vWf) in patients with acute coronary syndrome. ⋯ The serum concentration of soluble cell adhesion molecules was elevated significantly in patients with acute coronary syndrome. Successful reperfusion therapy was associated with a reduction in the serum concentrations of soluble cell adhesion molecules in patients with AMI.

Comparative StudyComparative frequency of bone sarcomas among different racial groups.
To analyse comparatively the relevant data from bone tumor registries in China, Japan, and the United States. ⋯ The findings from this analysis provide useful information for the epidemiologic study and the clinical diagnosis of bone tumors.

Additive potentiation by co-application of propofol and sevoflurane on GABA-induced chloride current in cultured neurons from rat dorsal root ganglia.
To investigate the effects of various concentrations of sevoflurane and propofol and a combination of the two agents on chloride current induced by bath utilization of 3 x 10(-6) mol/L gamma-aminobutyric acid (GABA) in the rat dorsal root ganglia neurons maintained in primary culture. ⋯ Either sevoflurane or propofol and their combination at clinically relevant concentrations potentiate the GABA-induced chloride current, which may at least partially contribute to the anesthetic mechanism. Additive interaction obtained with a co-application of propofol and sevoflurane may provide an evidence for a clinical combination of these two anesthetic agents.

Messenger RNA expressions of vasopressin system and aquaporin-2 in adriamycin-induced nephrotic rats and effects of astragalus membranaceus.
To investigate the expressions of hypothalamic arginine vasopressin (AVP) mRNA, renal AVP V2 receptor mRNA, and AVP-dependent aquaporin-2 (AQP2) mRNA in rats with adriamycin-induced nephrotic syndrome. Effects of Chinese herb Astragalus membranaceus (AM) were also tested. ⋯ The up-regulated mRNA expressions of hypothalamic AVP, renal V2 receptor and AQP2 might play a role in edema formation in adriamycin-induced nephrotic rats. AM exerts its therapeutical effects on nephrosis partially through this mechanism.

The diagnostic value of total respiratory impedance by impulse oscillometry in chronic obstructive lung disease.
To investigate the diagnostic significance of total respiratory impedance for chronic obstructive lung disease. ⋯ Resonant frequency was the most sensitive index in the parameters measured by IOS for diagnosing COPD. Since impedance measurement was a non-invasive method and only passive co-operation of the patient was needed. This technique could therefore be applied in COPD patients with acute attack for dynamic examination.
